Installation instructions

When connecting the cooktop to the gas supply with rigid pipes or a flexible hose (which must comply with BS 669 in the UK), make sure that:
you use rigid pipes or a flexible hose compliant with applicable local regulations. The flexible hose shall be of the correct construction for the type of gas being used and of the correct size to maintain the heat output of the appliance
the connection with rigid metal pipes does not cause stress or pressure to the gas piping. the flexible hose is not under tension, twisted, kinked, or too tightly bent, neither while the cooktop is in use nor while it is being connected or disconnected
the flexible hose is not longer than 2000 mm (or refer to applicable local regulations) and does not come into contact with sharp edges, corners, or moving parts, as these may cause abrasion. Use a single flexible hose only; never connect the cooktop with the more than one flexible hose. the flexible hose can easily be inspected along its entire length to check its condition; if it has an expiry date, it should be replaced before that date
if using a flexible hose which is not entirely made of metal, make sure that it does not come into contact with any part of the cooktop with a surface temperature of 70oC or above.
the rigid pipe or flexible hose is replaced if it shows signs of damage
the flexible hose is not subject to excessive heat by direct exposure to flue products or by contact with hot surfaces
the socket into which the plug of the flexible hose fit is permanently attached to a firmly fixed gas installation pipe and is positioned so that the hose hangs freely downwards.
the plug of the flexible hose is accessible after installation, so that it can be disconnected for service or removal
you inform the customer that the rigid pipe or flexible hose should not be subjected to corrosion by cleaning agents.
